Roberton is a large mutilated 12th century earthwork motte, probably founded by Robert the Fleming. Standing above a bend of the River Clyde, the motte is now a horseshoe shape, after a large northern trench was dug in the 1960s. Formerly with steep-sides, a flat-top and encased by a ditch, the possible site of a bailey is now occupied by farm buildings. There is evidence that timber structures once crowned the motte and the only fragment of pottery found, has been ascribed to the 14th century. A mile north-east is Bower of Wandel and 2 miles south-west is Nether Abington.
